KV3000 Kinematic Viscosity Bath
Operation and Instruction Manual
KV3000-Manual
-16-
NOTE: Do not attempt moving the bath
when filled with fluid medium. Drain all fluid
before moving or relocating the instrument. See
section 7.2 of this document. Sudden starting
and stopping could result in hot bath fluid being
forcefully ejected from the bath. It could also
result in overbalancing and tipping over the
instrument.
NOTE: Do not drain the bath until the fluid is at
ambient temperature.
Distilled water will be suitable.
Koehler supplies highly
refined white technical oil
(part # 355-001-001) that
contains an oxidation inhibitor
to limit clouding at higher
temperatures.
CAS# 8042-47-5
Minimum Flash Point: 120°C
(248°F)
Fire Point: 202°C (395°F)
Koehler supplies a clear
silicone heat transfer fluid
(part # 355-001-002) with high
oxidation resistance and low
volatility. CAS # 63148-62-9.
Minimum Flash Point: 200°C
(392°F).
NOTE: Do not use bath fluids that will
decompose or volatilize producing flammable
vapors below the maximum instrument operating
temperature +25°C.
NOTE: Coloration of the Mineral or Silicon Bath
Oil is an indication that the Medium must be
changed. See Draining instructions in section
7.3 of this document. When a decision is made
to discard this material, dispose of this material
and its container to a hazardous of special
waste collection point. Country, State, or local
laws may impose additional regulatory
requirements regarding disposal. Dispose in
accordance to all applicable regulations.
WARNING: Bath oils contaminated with
light ends can pose a flammability hazard.
5.2 Power
Turn on the main power switch to the unit.
WARNING: Do NOT turn the power on
unless the bath is filled with the proper medium;
otherwise, damage may occur to the unit and
the warranty would be void.
5.3 Starting a Test
Before running a test, make sure the unit is
level. Otherwise, the results will be affected.
1. Insert the Pt-100 RTD probe into the holder
provided at the top of the bath. Insert the
RTD connector into the receptacle located
on the rear panel
2. Install the appropriate ASTM thermometer in
the cover plate of the bath using the holder
provided.
3. Set the desired operation temperature using
the temperature control (See Section 4.3).
4. Install viscometer into its viscometer holder.
Carefully slide the holder onto the top of the
tube:
Figure 3
Charge the viscometer with sample and
carefully lower into the bath through the
viscometer ports.
WARNING: Do not test or run materials
that boil or exhibit high vapor pressure at the
bath test temperature.
